CALCULATING-MACHINE.

Patented Sept. 10, 1912.

Application filed February 23, 1912. Serial No. 679,522.

To all whom it may concern."

Be it known that I, GEORGE W. Gross, a citizen of the United States,residing at St. Louis, Missouri, have invented a certain new and usefulImprovement in Calculating-Machines, of which the following is a full,clear, and exact description, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, forming part of this specification, inwhich Figure l is a plan view of a calculating machine of my improvedconstruction. Fig. is a cross sectional View taken on the lines 2-2 ofFig. 1. Fig. 3 is a cross sectional view taken on the line 8-3 ofFig. 1. Fig. 4 is a perspective view of the forward end of an arm thatforms a connection between the worm shaft and the extensible scaleforming a part of my improved machine. Fig. 5 is an enlarged crosssectional view taken on the line 5-5 of Fig. 1.

This invention relates generally to calculating machines and moreparticularly to that class of machines utilized for multiplying ordividing in order to quickly and accurately ascertain a result where twofactors are known.

The machine herein shown and lescribed is particularly designed forreadily ascertaining the cost or selling price of cotton which isusually put up in large bales and the price per pound of which variesfrom day to day, and which cost or price sometimes goes into mills andfractional parts of mills. To correctly figure the cost or selling priceof a large number of bales of cotton of different weights and at a priceincluding cents, mills and fractional parts of mills per pound withoutthe use of some mechanical means or rate sheets involves considerabletime and labor, and it is the purpose of my invention to provide asimple machine which can be easily and quickly operated and which willaccurately indicate the results where a commodity is being bought andsold for an amount of money running into cents and mills and fractionalparts of mills.

In the following description the machine is referred to as beingparticularly adapted for calculating values and weights of cotton, butit will be readily understood that the same machine with changed scalesor indicating marks can be readily utilized for quickly and correctlyascertaining the weights and cost or selling prices of grain, hay coal,ore or any commodity that is sold in bulk or by weight, and said machinecan also be utilized for calculating taxes, interest and the like.

To the above purpose my invention consists in certain novel features ofconstruction and arrangement of parts hereinafter more fully describedand claimed.

In the construction of the machine as shown f make use of a rigid framecomprising a pair of vertically disposed end plates 10 and a series oflongitudinally disposed rails 11, the ends of which are rigidly fixed tosaid plates 10. The central one of these rails 11 is provided with aseries of marks 12 arranged in equal distance apart, which marks areconsecutively numbered so as to form a scale, which, in the presentinstance represent-s cents;

13 designates a shaft which occupies a po sition in front of the centralone of the rails 11 and the ends of this shaft are journaled in theplates 10. This shaft is provided with a right hand thread 14: and aleft hand thread 15 which are of the" same pitch and extending from oneend of the shaft to the other. Mounted on the right hand end of thisshaft outside the right hand plate 10 is a disk 16 having a milled edgewhereby it may be readily engaged and turned, and formed on the inneredge of this disk is an inclined face 17 provided with a graduated scale18 having 100 equal divisions, and formed on said inclined faceimmediately adjacent this scale is a second scale 19 having 32 equaldivisions. The scale 18 reprefrequently goes into eighths, sixteenthsand thirty-seconds of a cent.

Loosely mounted on the end of the shaft 13 adjacent to the right handplate 10 is a pointer 20, the outer end of which overlies correspondingend plate 10 is a set screw 23.

By loosening this set screw the pointer 20 may be adjusted as desired.

Fixed on the left hand end of the central one of the rails 11 is a block24, and pivotally mounted thereon is one end of a plate '25 which bearsloosely upon the rear one of the rails 11, and hinged to the upper endof this plate 25 is a corresponding plate 26. These plates 25 and 26 areprovided on their top surfaces with a graduated scale which is numberedfrom 350 at the lower end of the plate 25 to 700 at the lower end of theplate 26, and this scale represents the pounds of the commodity that isbought and sold. In the present instance this scale is numbered from 350to 700 for the reason that practically all bales of cotton weigh withinthese limits.

The lower end of the plate 26 is pivotally mounted on a sleeve 27, whichlatter is mounted to slide freely on the central one of the rails 11,and formed integral with and extending forwardly fromsaid sleeve is anarm 28, the forward end of which is provided with a split bearing 29.This bearing encircles the shaft 13, and formed on the interior of saidbearing is a spirally disposed rib or feather 30 that engages in theright hand thread 14: of the double threaded shaft13.

Mounted for sliding movement upon the lower front one of the rails 11and the shaft 13 is a carriage '31, and positioned thereon to the rearof the shaft 13 is a housing 32 in which is arranged a counting andindicating mechanism comprising a series of four or five disks orcounting wheels arranged side by side and connected so that when one ofsaid wheels or disks has made one revolution it operates the adjacentwheel or disk and moves the same one-tenth of a revolution, and likewisethe adjacent wheel upon making a complete revolution imparts partialrotation to the next adjacent wheel.

I make no claim about the particular form of counting and indicatingmechanism utilized, as there are a number of existing types of devicesthat eanbe obtained in the market and advantageously utilized with myimproved machine. Mounted on the shaft of this counting and indicatingmechanism is a pinion 33 with which meshes a larger pinion 34, and whichlatter is fixed to the hub of a disk 35 having a milled edge, andmounted for rotary movement upon the shaft 13. Fixed on the interior ofthe hub of this disk is a spirally disposed rib 36 that engages in theleft hand groove 15 of the shaft 13. Thus when the disk 35 is rotatedthe hub 36 engaged in the groove 15 will cause said disk, the carriage31 and the housing 32 to slide lengthwise upon the shaft 13 and thelower front one of the rails 11. At the same time the pinion 34 impartsrotary motion to the pinion 33, and as a result, the counting wheels ordisks within the housing 32 are correspondingly actuated. Fixed to thehousing 32 and projecting rearwardly therefrom in a plane immediatelyabove the plane occupied by the extensible scale comprising the plates25 and 26 is an arm 37. Carried by this arm is a transparent plate 38,and formed thereon is a longitudinally disposed line or mark 39 whichserves as a guide for positioning the counting and indicating mechanismrelative to the extensible scale. The position of the extensible scaleis con trolled by means of the disk 16.

The operation of my improved calculating machine is as follows: Assumingthat a buyer is purchasing a bale of cotton weighing 578 pounds at 11?;cerits per poundthe disk 16 is manually engaged and rotated so that thebearing 29 and sleeve 27 is moved into position so that the left handend of the sleeve 27 is in a position between the marks on the centralone of the rails 11, designated by the numbers 11 and 12, and theoperator now continues to rotate said disk 16 until the mark designatedby 75 of the scale 18 is tions the extensible scale comprising theplates 25 and 26 for retaining the total cost of the bale at a price of11% cents per pound, and the operator now rotates the disk 35 in theproper direction to move the carriage and counting and indicatingmechanism along the shaft 13 until the line 39 on the transparent plate38 is in a position directly above the point or indicating mark 578 onthe scale. During the rotary movement of the disk 35 the pinion 34imparts rotary movement'to the pinion 33 in turn actuating the countingwheels or disks within the housing 32 and when the parts have beenbrought to the proper position with the line 39 over the proper mark onthe ex tensible scale the counting wheels or disks will show through theopening in the top of the housing 32, the correct result of 57 8multiplied by 11%, namely 6791, which is the value in dollars and centsof the bale of cotton under consideration.

It will be readily understood that the operations just described andwhich consist of manually rotating the disks l6 and 35 can be veryrapidly performed, and thus where a large number of bales of cottondiffering in weight are being sold much time and labor is saved inascertaining the exact price to be paid for each individual bale.

As hereinbefore stated, my improved calculating machine can beadvantageously used for ascertaining the price of any commodity which issold by weight and at varying prices per pound, as, for instance, wagonand carloads of grain, coal, mineral, baled hay or any commodity that issold in bulk and at prices which fluctuate from day to By changing thenumbers upon the scales a machine of my improved construction may beadvantageously employed in ascertaining taxes, interest and for any andall calcu lations where two factors are known. W here a large amount ofa certain commodity is purchased for a lump sum price and it is desiredto quickly ascertain the exact price per pound paid for the commoditythe operator rotates the disk 35 until the number representing the pricepaid appears on the counting and indicating wheels through the openingin the top of the housing 32, and the disk 16 is now rotated until theline 39 is directly over the mark on the extensible scale indicating theweight of the commodity, and when these operations have been completedthe parts will be so positioned as that'the price per pound is indicatedby the position of the.

sleeve 27 on the central one of the rails 11 and the position of thescales on the disk 16 relative to the indicating mark 21 on the finger2-0. 7

It will be readily understood that minor changes in the size, form andconstruction of the various parts of my improved calculating machine canbe made and substituted for those herein shown and described withoutdeparting from the spirit of my invention, the scope ofwhich is setforth in the appended claims.
